Bakugou X Kirishima's sister (Reader)

Chapter 39

Your friends were chatting happily, working on homework, discussing their weekends as you sat at the table in the common room. Your group had gotten larger, with you now rejoining them and Denki bringing Jirou, so they could spend time together.

You sat there trying to focus on your work, not saying much, your head still reeling with thoughts from your discussion with Kyoko. Before you walked downstairs you had received a message from Hoshi, apologizing profusely for the situation. He was apparently unaware of the contract also, but you weren't sure if you believed him. How could he not know?

"Hey, dumbass," Katsuki's pencil tapping your forehead, bringing you back to your table of friends.

"Huh? What?" You blinked, realizing Katsuki had been talking to you. He had been helping Sero with the math problem you were working on before he turned towards you.

"You're not going to argue over who got the correct answer?" He questioned you, "I can see you wrote down something different."

You looked down at your paper and then at Katsuki's.

"Actually, you're probably right, I've been a little out of it," you erased your answer, starting over, this time actually paying attention to what you were doing. He gave you a weird look, but he couldn't say anything before Mina spoke.

"Bakugou, you can't call your girlfriend that, it's rude."

He looked at her, face scrunched together, wondering who the hell asked her. "I can call my girlfriend whatever I want." He scoffed at her.

She looked at you, but you weren't paying attention still working on the math problem. Her eyes moved on to the next person to back her up, "Kiri, are you just going to let him talk to your sister like that?"

Eijiro glanced at you and then Bakugou and finally looked at Mina. "Don't look at me, I'm not getting into their business anymore."

She huffed before she finally locked eyes with you. You had just finished up with your work and now looked up from your papers ready to rejoin the conversation.

"Do you really not care that he calls you that?"

"Calls me what?" Your eyebrows knitted together in confusion, your brain only picking up about half of the conversation.

She gave you a look, "You don't care that he calls you a dumbass?"

"No?" you elongated your response, making it into a question as your head tilted to one side. "Am I supposed to?"

"Yes!" she was beyond exasperated at this point, confused that no one else saw the problem with it, "You should definitely care about what your boyfriend calls you. There is nothing sweet or caring about 'Dumbass'."

"I don't know," you shrugged, "I guess that's just what he's always called me, so I never really noticed it before."

Katsuki gave Mina a smug look before he glanced back at you. His eyes held concern for how you'd been acting today, not sure why you seemed so out of it.

"Alright can we talk about something else?" Sero spoke up, "Sitting between two couples really puts it into perspective how lonely you are." His face displayed pain as he regretfully sat between Denki and Katsuki.

Mina rolled her eyes, dropping the conversation before going back to her work. All of you quieted down as you finished up with which ever assignment you'd been working on. Katsuki glancing at you every so often but he never said anything, just tried to read your face when he thought you weren't paying attention. An hour or so had passed when your group finally decided to disperse, Denki and Jirou the first two to get up. Sero got up next, walking to the side of the table Mina and Eijiro sat on, talking about a new video game he got.
